HEATER.

Application filed January To (6 whom it may concern: 8

Be it known that 1, EPI-IRAIM lVrrMAN, a citizen of the United States of America, and a resident oi Sinking Spring, in the county of Berks and Eitate of Pennsylvania, have invented a new and Improved Heater, of which the following is a description.

My invention relates to the heater of a heating system.

The general object of my invention is to provide a battle or draft regulator in. association with the flue of the heater.

The nature 01 the invention and its distlnguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example 0 t the invention.

Figure 1 is a side elevation of a heater embodying my invention, showing the same partly broken away;

Figure 2 is a plan view of the heater and its appurtenances;

lFigure 3 is a detail in vertical section on the line 3-3, Figure 1;

Figure 1 is a plan view of the battle or flue regulator.

In carrying out my invention in accordance with the illustrated example, the heater designated generally by the numeral 10 is provided with a water jacks; designated 11 and flrepot 12. The numeral 13 indicates the flue and 1 1- an opening in the top of the heater through which fuel may be entered, said opening 14: being closed by a cover 15.

In order to modify the draft from the firepot 12 to the flue 13, I provide in the firepot adjacent to the out ance of said flue a regulator designated generally by the numeral 16 and embodying an arcnate plate presenting concave-convex edges. From the arouate plate of the regulator there rises a semicylindrical vertical wall or flange 17 which is disposed beneath and in register with the fuel opening 1 1. Thus, fuel may be passed freely through the opening 1 1 and through the vertical flange '17 and said flange extends in an arc in front of and adjacent to the entrance of the flue 13,, while the arcuate plate of the regulator 16 closes direct entrance to said flue at the base of the flue and beyond the same at each side of the regulater 16. The provision of the regulator 16 28, 1925. Serial N0. 5,302.

positioned as described prevents direct upfiow of products 01 combustion from the firebox to the flue 13 and battles said products so as to require them to pass about the sides of the flange 17 to find escape through the flue. For securing the regulator 16 in position there is formed a horizontal flange '18 at the top of the vertical flange 17, said flange 18 having a bolt hole 19 through which the bolt 20 is passed, the bolt extending through the top of the heater 10 and receiving a nut 21.

The numeral 22 indicates a damper on the base of the furnace and 23 indicates a damper at the exterior of the flue 13 and leading thereto. To said damper 22 is cured the lower end of a connecting rod 24 the upper end of which is secured to an arm 25 on the upper damper 23. Between the ends of the rod 24 as, at 26 is secured the end of an arm 27 on a thermostatic diaphragm 28 of known form which need not be further referred to except to say that said thermostat 28 is secured by clamp bands 29 to the outlet pipe leading from the water jacket 11.

The assemblage composed of the dampers 22 and 23 and rod 24: is such that movement of said rod longitudinally in one direction will exert a closing action on one damper and an opening actlon on the other damper.

I would state further that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described my invention, 1 claim: a

In a heater having a firepot, an opening in the top of the heater for the entrance of fuel, and a flue leading from the heater at the top of the firepot; a baflle device including an arcuate plate below the inlet to said flue, a semi-cylindrical flange rising from said plate and in register with said fuel opening for the passage of fuel through said opening and through said semi-cylindrical flange to the firepot, a horizontal flange on said semi-cylindrical flange at the top of the same, and a bolt securing said horizontal flange to the heater at the top.
